to Remove GHS Blower Drive Belt
IMPORTANT: With the belt removed, the blow-
er wheel must spin freely. Any binding or drag-
ging of the wheel is an indication of dirt build-
up. This buildup must be cleaned to avoid
abrasive wear of the blower blades, ex cessive
power loss and eventual loss of blower perfor-
mance (clogging).
2. Use a pressure washer or water spray, and di-
rect the spray inside the blower housing against
the blower blades. Water pressure will cause
the blower wheel to begin to spin and the com-
bination of spinning action and water will eec-
tively wash the inside of the housing. Spray
may be directed against the blower blades ver-
tically and horizontally to cause rotation in both
directions for thorough washing action. Wash
blower until the blower wheel spins freely in
both directions.
3. Reinstall the GHS blower drive belt by reversing
the removal procedure.

Hydrostatic Transmission Cooling Fins
Keeping the cooling ns on the hydrostatic trans-
mis sions clean and free of obstruction is essential
to avoid overheating the transmission uid and
short ening transmission life. The cooling ns should
be checked every 100 hours and cleaned if neces-
sary.
To clean the ns, use compressed air and/or a pres-
sure washer. The cooling ns extend all the way
around the housing–the ns underneath need to be
clean as well as the more visible ns above. Also,
pay close attention to the area under the drive pul-
ley.
IMPORTANT: In case an oil leak develops on the
input shaft, the cooling fan blowing dusty air and oil
on the transmission will quickly pack the cooling
ns with oily dirt. If this condition occurs, replace
the seal immediately to avoid overheating and dam-
aging the transmission. The input shaft assembly
and seal are easily replaced without removing the
transmission from the machine.
An additional procedure in maintaining transmission
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.
